Water is a polar molecule and thus diffuses slowly into cells. what type of membrane protein would you expect to find many of in a cell that must be highly permeable to water?

Aquaporins

Explanation:

Aquaporins are the transmembrane protein channels formed by integral proteins. Their function is to allow the rapid movement of water molecules across the cell membrane. Being a polar molecule, water can diffuse only slowly through the membranes. The presence of aquaporins allows the cells to quickly move the water across the membranes. For example, nephrons of kidneys, red blood cells have a higher concentration of this protein in their membranes.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called

more words for this could be abiotic and biotic

abiotic: living organisms within an ecosystem

biotic: non-living organisms within an ecosystem
